Background : The purpose of this study is to investigate the effect of split application and adapted fertilization application cultivation in stable medicinal herbs production of Angelica acutiloba K. And it accomplished one’s purpose to GAP guide manual established standard method of cultivation technology, contribute to the enlargement of farm’s income. Methods and Results : Method of fertilization application were conducted under four condition compose to standard application (N-P-K-Compost: fermented mixed oil cake fertilizer applied at 14-10-10-600 ㎏․10 a−1cultivation. Compost and fused phosphate applied at 100% of basal fertilizer in April 14. The split application level of standard application (N-K) applied at 100%, 50%, 40%, 30% of basal fertilizer in April 14, 50%, 40% and 30% of top dressing were two, three times application (N-K) in June 1, July 15, August 15, 25% and 20% respectively. Sowing dates with Jangsung varieties in April 28 of the year 2015. Planting density were spaced 30 ㎝ apart in rows 15 ㎝ apart with black color non-woven cloth covering open cultivation by level row 90 ㎝. Plot design randomized block 3 repetition. Conclusion : Growth characteristics by 50%, 70% and 60% of top dressing were two, three times application (N-K) in June 1, July 15, August 15 compared to standard application (N-K) applied at 100% basal fertilizer, aerial part as a result were so many such amount of growth as number of leaf per plant, etc., Length of leaf and main root of aboveground, subterranean part growth increment rising highest. Dried roots yields compared to standard fertilizer 100%application (217 kg․10 a−1) treatment. 50%, 70% and 60% of top dressing were two, three times application (N-K) increased by 6%, 14%, and 18%. respectively.
